  • Supply Voltage: 3.3V to 5V
  • Detecting sound intensity
  • Interface: Analog
Sample code:
void setup()
{
Serial.begin(9600); // open serial port, set the baud rate at 9600 bps
}
void loop()
{
int val;
val=analogRead(0); //connect mic sensor to Analog 0
Serial.println(val,DEC);// print the sound value to serial monitor
delay(100);
